Hi, could you elaborate what/why you want to test an external api?

kiquenet commented 2 years ago

2 scenarios:

1) Test any exteranl REST API Client (ApiClient), for example, or using any REST API of another departaments (Sales, Purchasing, Accounts, Finance , Human Resources, ...), we haven't source code but we need test "API client".

2) Test our internal REST API (webapplicationfactory)

YOU'RE USING HTTPCLIENT WRONG AND IT IS DESTABILIZING YOUR SOFTWARE
